namd cvs memory leak?

Dear all:

While using the NAMD CVS version, I found a memory leak problem. After
500,000 steps simulation, the memory usage goes from 76.781250 MB to
93.515625 MB. The relatively small amount of increase might not be a
big deal. However, I do intend to run long simulations, and the
clearly increasing trend would become a problem then.

Has anyone else noticed this also?

Best,
Bin
